vue-lazy-renderer

Lazily render Vue.js components for performance.

Feature

• Speed. Use the Intersection Observer API (IO) to prevent performance problems.
• Degrade Gracefully. If a user's browser doesn't support the IO, use getBoundingClientRect instead. (vue-lazy-renderer does not load the IO polyfill—it is too fat. You can load it by yourself.)
• Lightweight. Only 3.7 kB minified.
• Highly Customized. You can globally set several options and locally override them.

Installation

npm:

npm install vue-lazy-renderer

Yarn:

yarn add vue-lazy-renderer

Usage

Registration

Use a plugin to register a global component:

import VueLazyRenderer from 'vue-lazy-renderer';
import Vue from 'vue';

Vue.use(VueLazyRenderer);
